- Valve clearance......(Cold) Intake....0.05mm~0,09mm (0.002in~0.004in)
- Exhaust....0.15mm~0.19mm (0.006in~0.007in)
- Main jet #125 / #36

- Needle Jet/Jet Needle.........V95 / 5C20-1

- Idle RPM....1400 ~ 1600rpm

All that was found on yamaha motor.com ..I actually don't know why i typed all that

***Quick question ...The fork oil is 10wt at 352cc ..how many cc's/how much would i need to top them up to feel a difference??

I know, don't you love it! I wish all manufacturers would put specs online.

You don't need to top up the fork oil, because the level will do nothing, you simply want it above the dampening rod. To make a difference you can either go to a heavier or lighter weight of oil, or re-shim.

Good luck!

Oil level not critical? News to me, used to see a lot of recommendations, at least before USD forks to add until it was 6" from the top of the tubes. I knew a guy who topped them off, rode like a brick until he blew out the fork seals. Ron
